To all whom it may concern."

. ence being had therein to the accompanying drawing.

This invention pertains to a newand useful fan, designed especially to be operated by a spring motor, so as to allow the fan to be conven ently moved from one place to another; furthermore, the invention sets forth, asan essential object to provide a device .ofthis particular character, which is simple and inexpensive to manufacture and very effective in practical use.

A further object is to provide a fan can I'ying shaft, which may be removed, without disturbing the governor which will be left depending from the inside of the casing,"

which supports the fan proper, as will be clearly depicted in the drawings.

This invention comprises further objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereoflwill be pointed out by the appended claimQ To obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages,

. reference is to be had to the hereinafter set .3

forth description and the accompanying drawings in connection therewith, wherein, Figure 1 illustrates a perspective view of the fan, showing the same carried by a podestabcabinet, which tapering toward its upper" end. Fig. 5?: is a sectional view on line 2-2 of F 1, showing a particular journal for the fan-cariying shaft. Fig. 3 is a sectional view on line 3'-3 ofFig. 2. Fig. 4 is a sectional view on line 4-4: ofFig. 3. Fig. 5 is a plan view of the brake shoe.

Making, renewed reference to the accompanying "drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures, 1 designatcs a suitable cabinet of any desired form, but the present application, the. ap plicant prefers a cabinet which is tapering toward its upper end. in. this cabin t, is journalcd a plurality of shafts 2, upon each one of which, is journaled, a pinion 3 and a s ur ear 4 which forms a chain of ears suitable for transmitting motion from the clutch controlled gear 5, loosely journaled' i 7 upon the shaft 6, which is journaled' in the lower portion of the cabinet, as clearly shown. 1

Splined to-the shaft 6, is a clutch mem her 7, which is designed to engage the clutch teeth 8, formed with the gear 5 a coil spring is mounted upon the shaft 6 and disposed between the clutch member 7 and the side ofthe cabinet. ,When the shaft 6 is rotated I in one direction, the winding of the spring is caused, but when the said shaft is rotated in the opposite direction by the unwinding of the spring 10, the gears are operated, which will causemotion to" be transmitted to the fan-carrying shaft, through the medium of the bevel pinion 11., carried at the lower end of said fan-carrying shaft. This fan carryr ing shaft lfi is composed of two sections (rand b, which are caused to rotate together by means of a rectangular lug and recess 0 and (Z, so as to transmit motion to the upper section of the shaft and to the fan, as will be clearly evident from examination of Fig.

2 of the drawings. By constructing the shaft in two sections, the upper portion may be removed without disturbing lower section. The shaft 6, is provide with a crank handle 12 for the purpose of windthe ing the springglO. The up er end of the fan carrying she is provide with a plurality of vertically disposed recesses 13, which neceive the bevel enlargements formed with the fan blades, 14, as shown. To prevent the fan. blades from displacement vertically, a winged init is provided, which is threaded upon the upper end of said shaft. The upper portion of the cabinet through which the fan carrying shaft passes, is provided with an upper and lower ball bearing journal box 16, the securing late 17, of the upper one, maybe remove so as to allow the fan carrying shaft to be removed from its journal, without disturbing the mounting of the governor 18, the upper sleeve of which, designated by the numeral'19, is provided with a rectangular aperture 20 designed to engage the square portion of the faipcarrying shaft, so to cause'the governor to rotat with the shaft. "When the faii carrying s "t is rotated at a high rate of speed, the s of the governor will be forced outward thereof by the centrifugal force, thereby. regulating the speed of the shaft. The arms 18 to whichthe halls of the governor are attached, have a sleeve 18* connected to'their lower ends, and which is slidable upon the shaft of the fan; These balls are forced outward by centrifu al force, which causes the arms 18, to a so swing outward until they contact withthe shoe 21,, of the rod 21, which rod is ad- Eistkble'by means of a thumblnut 22, as will readily understood. The rod 21 is pro- I vided witha collar 21 between which, and

the casing a spring 21 is disposed, against the tension of which, the arms 18.,act; A

suitable braking device 21 is provided, and

p "which is spring actuated, and is'designed to forme in the end of the bracket '24, bolted or otherwise secured to the side of the cabi engage the upper sleeve of the governor; the shaftof the braking'deviceis regulated by a thumb screw 22. The lower end of the fan carrying shaft is conical so to have a needle bearin within a conical shaped recess 23,

net.

- It is to be understood that various changes and modifications maybe employed in the construction and embodiment thereof, combinations of features, and elements, without in any way departing from the spirit and scope of the invention covered by the claim thereof: it being understood thatJvhatever variations or modifications are employed m'ust fallwithin the scope of the appended claim. From the foregoing the essential features,

, states elements and the operation of the device, to gether with the simplicity thereof, will he clearl apparent, and when manufactured in accordance with the invention, an inexpensive market will be easily obtained therefor.

Having thus described the invention, what is claimed by the protection of Letters Patent, is:

In a device as set forth, a casing, a spring motor mechanism disposed therein, a tancarrying shaft operated by said motor mechanism, said casing havingoa ball bearing for the fan-carrying shaft,comprising up er and lower plates forming be secure to the upper and lower faces of t e easing, a

slidable removable sleeve having a rectangular bore, said fan-can ing shaft hein pro vided with a rectangui ar portionto t said bore to cause the two, to rotatetogether,
